Question about Yongnuo YN-E3-RT II

The Yongnuo YN-E3-RT II is a wireless remote trigger for Canon cameras, designed to control RT-compatible flash units. It is compatible with a wide range of Canon cameras, including recent models such as the Canon EOS RP. Although the search results do not explicitly mention compatibility with the Canon RP, given that the YN-E3-RT II is compatible with many Canon models, it is likely that it will work with the Canon RP, provided that the flashes used are compatible with RT technology.

To ensure compatibility, be sure to use RT-compatible flash units, such as the Canon 600EX-RT or Yongnuo YN600EX-RT. The YN-E3-RT II offers advanced features such as high-speed sync, group control and colour temperature communication.

If you're having connection problems, check that the firmware on the devices is up to date, as this may resolve some compatibility issues.
